Water & Sewer Construction Works

Water and sewer construction works can form part of an approved development and may be necessary to provide infrastructure, or the extension of infrastructure, for connection to Council’s water supply or sewerage systems. 

Pipe Inspection

Prior to construction

Prior to issue of a Construction Certificate or Subdivision Works Certificate, you may be required to submit water and sewer design plans for Shoalhaven Water’s approval. Where a Complying Development Certificate is issued, then the design plans are prepared and approved prior to the commencement of any works. The design plans must be approved by Shoalhaven Water before a Certificate can be issued.

The design plans must clearly indicate:

  • What infrastructure is to be constructed, what is existing, and what is to be modified,
  • Details of the development including lot layout, contours, buildings and structures (existing and proposed), vegetation, other infrastructure,
  • Construction notes, procedures, practices,
  • Staging of work (if staged).

Other documentation required include work method statements, soil erosion and sedimentation control plans, detailed engineering calculations, and detailed strategy reports.

Water and sewerage design plans need to be prepared by a suitably qualified consultant to Shoalhaven Water’s specifications. Please refer to Guides, Resources and Standards for relevant documents.

How do I submit design plans?

Design plans can be submitted by using our online Information & Support Documentation Submission form. Associated fees will be invoiced to the applicant or nominated person or company.

A pre-commencement meeting will be held on site and the Shoalhaven Water officer or inspector will provide approval for the work to commence.

Inspection of the water supply and/or sewerage works are required as the works are being constructed where it is intended for the works to be transferred to Council’s ownership.

Work-As-Executed (WAE) Plans

Submission of Work-As-Executed (WAE) plans

WAE plans are required to be prepared and submitted to show Shoalhaven Water the actual position of the constructed assets. The plan is recorded in our system and is used for future planning and maintenance purposes. The documents are also used to provide information to customers about Council’s assets.

WAE plans can be submitted via email: swdevelopment@shoalhaven.nsw.gov.au

Who prepares Work-As-Executed plans?

All WAE plans must be prepared by a registered surveyor in accordance with Shoalhaven Water's Survey Plan Preparation & Work-as-Executed document. Please refer to Guides, Resources and Standards for the relevant documentation.
